This may seem left field, but I am working on a custom application. I have need to access a Com Port resource that is registered in Windows as an COM asset. Ex. the program talks to UUT through COM1. What I would like to do is talk to UUT through ethernet as "COMX" asset, X being 3-16. Is there "canned" installer to do such? This would would be awesome, if not no problem I will write it myself. The UE9 is a great little product .

Are you saying you want to use Windows COM port drivers (serial port) to communicate with a UE9? That would require a special virtual com port driver. We have not developed one or used one, but there might be one available that work work.

Yes, that is the jist. I am accessing an executable that creates a "server" to the COM ports and using the Window com drivers would allow me seemless access through this software. The end goal is to have a DAC and serial port on the ethernet bus, without having to and maintain a PC. Its been done in industrial applications for sure, not sure if its been done like using this method.

I believe from the way Windows handles ethernet devices, as long as you can get that COM port to list itself under windows as a valid ethernet connection with valid TCP settings. I know this is commonly done with USB -> ethernet devices, so it is possible. I'm not aware of an existing method of doing this for a COM port but it wouldn't surprise me if there is one out there.

How about Perl support for the UE9 ? UE9 has a serial port-- could I run RS-232 to it and retrieve via ethernet ?
My environment is Debian Linux. We love Perl as a test language. Python not so much.
Is LJFuse up and running for this project ?
Thanks.

To provide more information on serial communication low-level functions, refer to the sections 5.3.17 - 5.3.19 in the UE9 User's Guide.

At the moment we do not provide any Perl wrappers or interfaces for the UD devices, though I can look into that. Currently if you want to get working in Perl you can look into using the low-level function or Modbus protocols and communicating through ethernet. There is also the option of using LJFuse or LJSocket (both support Linux and Mac OS X), which provide a file IO or TCP socket interface which should be accessible through Perl.
